The Ever Widening Gyre: Factors Affecting Change in Adult Education Graduate Programs
The purpose of this survey study was to understand the factors that have influenced recent changes in the size of adult education graduate programs. We found that integration has a significant effect on changes in student enrollment while leadership, innovation, and integration all significantly predict variance in faculty growth
Reproductive Regrets Among a Population-Based Sample of U.S. Women
Women have many reproductive options, but little is known about their regrets regarding prior reproductive choices and outcomes. Guided by the life-course and stratified reproduction perspectives, this study draws on an open-ended question about reproductive regrets from wave I of the National Survey of Fertility Barriers, a representative telephone survey of reproductive aged U.S. women conducted from 2004 to 2006. The authors classified regrets into five broad categories: (1) none, (2) problematic fertility, (3) unfulfilled fertility desires, (4) family, and (5) pregnancy experiences. The authors conducted the analyses separately by motherhood status. Logistic regression analysis revealed that regardless of parental status, those who were older, had infertility, or were experiencing economic hardship were more likely to report reproductive regrets. The authors also investigated factors associated with the likelihood of expressing specific reproductive regrets. In general, the present findings confirm expectations based on the life-course and stratified reproduction perspectives
Change in Motherhood Status and Fertility Problem Identification: Implications for Changes in Life Satisfaction
Objective: To determine whether the association between changes in life satisfaction and becoming a mother (or not) depends on fertility problem identification status.
Background: Evidence and symbolic interactionist theory suggest that, for women who initially perceive a fertility barrier, gaining the valued identity “mother” should be associated with increases and continuing to face a blocked goal (i.e., not becoming a mother) should be associated with decreases in life satisfaction.
Method: This study used the nationally representative two-wave National Survey of Fertility Barriers to conduct a change-score analysis with chained multiple imputation. The focal dependent variable was change in life satisfaction. Focal independent variables were Wave 1 life satisfaction, fertility problem identification status, and birth between waves, controlling for stability and change in relationship status, talking to a doctor about how to get pregnant, religiosity, social support, importance of parenthood, importance of leisure, importance of work success, and economic hardship.
Results: Among women who perceived a fertility problem at both waves, becoming a mother was associated with increased life satisfaction and not becoming a mother was associated with decreased life satisfaction. Women who gained or lost a fertility problem perception between waves but did not have a live birth experienced a gain in life satisfaction between waves, suggesting the relevance of the duration of fertility problem perception for change in life satisfaction
Relationship Satisfaction Among Infertile Couples: Implications of Gender and Self-Identification
We use path analysis to analyze heterosexual couples from the U.S. National Survey of Fertility Barriers, a probability-based sample of women and their male partners. We restrict the sample to couples in which the women are infertile. We estimate a path model of each partner’s relationship satisfaction on indicators of self-identifying as having a fertility problem or not at the individual and couple levels. We find a gender effect: for women, but not men, relationship satisfaction was significantly higher when neither partner self-identified as having a fertility problem. Women’s relationship satisfaction exerted a strong influence on their partners’ relationship satisfaction, but no similar association between men’s relationship satisfaction and their partner’s satisfaction was found. In infertile couples, higher levels of perceived social support are associated with higher levels of relationship satisfaction for women but not for men
HQET at order : II. Spectroscopy in the quenched approximation
Using Heavy Quark Effective Theory with non-perturbatively determined
parameters in a quenched lattice calculation, we evaluate the splittings
between the ground state and the first two radially excited states of the
system at static order. We also determine the splitting between first excited
and ground state, and between the and ground states to order

The Earth System Governance Project as a network organization: a critical assessment after ten years
The social sciences have engaged since the late 1980s in international collaborative programmes to study questions of sustainability and global change. This article offers an in-depth analysis of the largest long-standing social-science network in this field: the Earth System Governance Project. Originating as a core project of the former International Human Dimensions Programme on Global Environmental Change, the Earth System Governance Project has matured into a global, self-sustaining research network, with annual conferences, numerous taskforces, research centers, regional research fellow meetings, three book series, an open access flagship journal, and a lively presence in social media. The article critically reviews the experiences of the Earth System Governance network and its integration and interactions with other programmes over the last decade
What factors in rural and remote extended clinical placements may contribute to preparedness for practice, from the perspective of students and clinicians?
What factors in rural and remote extended clinical placements may contribute to preparedness for practice, from the perspective of students and clinicians? Michele Daly, David Perkins, Koshila Kumar, Chris Roberts and Malcolm Moore Background: Community based rural education opportunities have expanded in Australia, attracting more medical students to placements in rural and remote settings. Aim: To identify the factors in an integrated, community engaged rural placement that may contribute to preparedness for practice (P4P), from the perspective of students and clinicians Methods: Forty two semi-structured interviews with medical students, supervisors and clinicians analysed thematically. Results: Opportunities for clinical learning, personal and professional development and cultural awareness were reported by students and clinicians as key factors that contribute to preparedness for practice. Potential barriers in rural and remote settings included geographical and academic isolation, perceived educational risk and differing degrees of program engagement. Conclusions: A longitudinal clinical placement in a rural setting may enable development of enhanced competencies leading to P4P. A rural setting can help provide a unique experience through hands-on learning, enhanced personal and professional development opportunities and observation of the cultural and contextual impact on health
Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector
A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
Changes in health in England, with analysis by English regions and areas of deprivation, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013.
BACKGROUND: In the Global Burden of Disease Study 2013 (GBD 2013), knowledge about health and its determinants has been integrated into a comparable framework to inform health policy. Outputs of this analysis are relevant to current policy questions in England and elsewhere, particularly on health inequalities. We use GBD 2013 data on mortality and causes of death, and disease and injury incidence and prevalence to analyse the burden of disease and injury in England as a whole, in English regions, and within each English region by deprivation quintile. We also assess disease and injury burden in England attributable to potentially preventable risk factors. England and the English regions are compared with the remaining constituent countries of the UK and with comparable countries in the European Union (EU) and beyond. METHODS: We extracted data from the GBD 2013 to compare mortality, causes of death, years of life lost (YLLs), years lived with a disability (YLDs), and disability-adjusted life-years (DALYs) in England, the UK, and 18 other countries (the first 15 EU members [apart from the UK] and Australia, Canada, Norway, and the USA [EU15+]). We extended elements of the analysis to English regions, and subregional areas defined by deprivation quintile (deprivation areas). We used data split by the nine English regions (corresponding to the European boundaries of the Nomenclature for Territorial Statistics level 1 [NUTS 1] regions), and by quintile groups within each English region according to deprivation, thereby making 45 regional deprivation areas. Deprivation quintiles were defined by area of residence ranked at national level by Index of Multiple Deprivation score, 2010. Burden due to various risk factors is described for England using new GBD methodology to estimate independent and overlapping attributable risk for five tiers of behavioural, metabolic, and environmental risk factors. We present results for 306 causes and 2337 sequelae, and 79 risks or risk clusters. FINDINGS: Between 1990 and 2013, life expectancy from birth in England increased by 5·4 years (95% uncertainty interval 5·0-5·8) from 75·9 years (75·9-76·0) to 81·3 years (80·9-81·7); gains were greater for men than for women. Rates of age-standardised YLLs reduced by 41·1% (38·3-43·6), whereas DALYs were reduced by 23·8% (20·9-27·1), and YLDs by 1·4% (0·1-2·8). For these measures, England ranked better than the UK and the EU15+ means. Between 1990 and 2013, the range in life expectancy among 45 regional deprivation areas remained 8·2 years for men and decreased from 7·2 years in 1990 to 6·9 years in 2013 for women. In 2013, the leading cause of YLLs was ischaemic heart disease, and the leading cause of DALYs was low back and neck pain. Known risk factors accounted for 39·6% (37·7-41·7) of DALYs; leading behavioural risk factors were suboptimal diet (10·8% [9·1-12·7]) and tobacco (10·7% [9·4-12·0]). INTERPRETATION: Health in England is improving although substantial opportunities exist for further reductions in the burden of preventable disease. The gap in mortality rates between men and women has reduced, but marked health inequalities between the least deprived and most deprived areas remain. Declines in mortality have not been matched by similar declines in morbidity, resulting in people living longer with diseases. Health policies must therefore address the causes of ill health as well as those of premature mortality. Systematic action locally and nationally is needed to reduce risk exposures, support healthy behaviours, alleviate the severity of chronic disabling disorders, and mitigate the effects of socioeconomic deprivation.
